A three-dimensional ecological interlocking block with large porosity

Abstract

The invention discloses a large-porosity type three-dimensional ecologic interlocking block. The large-porosity type three-dimensional ecologic interlocking block comprises a surfacing, the surfacing is in a square shape, a square hole forming area is arranged in the middle of the surfacing, upward stand columns perpendicular to the surfacing are arranged on the corners of the surfacing, hasp structures perpendicular to the corresponding side edges are arranged on the midpoint positions of the two adjacent side edges of the surfacing, grooves used for being connected with the adjacent interlocking block hasp structures in an embedded mode are formed in the midpoint positions of the other two side edges, and tooth sills are formed on protruding portions in the downward direction of the grooves. The interlocking block has the advantages of being good in stability against sliding, strong in abrupt slope adapability, capable of achieving interlocking between blocks, good in self-confinement, capable of reducing differential settlement, capable of achieving energy dissipation and anti-scouring effects, high in aperture ratio, good in hydrophilic intercommunity, large in ecological space, uniform in hole forming, strong in landscape, controllable in precast block quality, convenient and fast to construct, and capable of maintaining the practicability of riverway revetment by working cooperatively with the ecological system.

Description

technical field [0001] The invention relates to a slope protection building component, in particular to a large-porosity three-dimensional ecological interlocking block. Background technique [0002] With the rapid development of the regional economy of various rivers, new river channels will replace the traditional channel structure types. While meeting the functions of pilotage, anti-collision and bank protection, etc., it is necessary to take into account the restoration of the original river ecological environment. Coordination of natural environment, ecological community, social and human factors. Therefore, the traditional large-scale concrete and riprap channelized impermeable rigid revetments are gradually replaced by flexible, small-scale, internally and externally permeable ecological revetment structures. [0003] In recent years, the ecological revetment structure can be divided into two parts. One is the wall revetment structure, which excavates the natural riv...

Problems solved by technology

However, the prefabricated concrete ecological interlocking blocks commonly used at present are all planar structures, and the slope protection pavement is formed through the interlocking action between the blocks, and the overall friction is used to play an anti-sliding effect, but there are the following problems: ① When the slope is steep, the gravity sliding force component The overall stability of the slope protection structure cannot be guaranteed; ②The anti-scouring performance of the planar structure is limited. If the filter layer is not laid properly, the soil will be taken away from the opening by wave climbing and heavy rainfall erosion, affecting the overall stability; ③ The high opening ratio reduces the weight and friction contact surface of the planar ecological block, which affects the anti-sliding stability, but the insufficient opening ratio will reduce the living space of plants; ④ Due to the lack of sufficient energy dissipation measures for the protective surface, if the timing Improper, vegetation will be washed away by waves during the transition period, and it is not easy to survive
